The present document is part 2 of a multi-part standard covering the V5.1 interface specification as described below:

Part 3: "Test Suite Structure and Test Purposes (TSS&TP) specification for the network layer (AN side)";

Part 4: "Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing (PIXIT)

To evaluate conformance of a particular implementation, it is necessary to have a statement of which capabilities and

options have been implemented for a given Open Systems Interconnection (OSI) protocol. Such a statement is called a

NOTE: It is however possible to use the present document to indicate the basic requirements for an Access

Network (AN) or a Local Exchange (LE) required by a network operator. Specific requirements need to

be added, e.g. the Public Switched Telephone Network (PSTN) port characteristics and conditions.

This second part of EN 300 324 defines the Protocol Implementation Conformance Statement (PICS) proforma for the

implementation flexibility allowed for a V5.1 interface defined in EN 300 324-1 [1]. It allows either the Network

Operator to formulate the requirements for V5.1 interface implemented in an Access Network (AN) or Local Exchange

(LE), or to decide whether an implementation meets these requirements. It details in tabular form the implementation

options, i.e. the optional functions additional to those which are mandatory to implement.

The present document is in compliance with the relevant requirements and in accordance with the relevant guidance
